the term mitral valve prolapse (mvp) is used for a particular subset of patients with hyperadrenergic dysautonomia. it occurs when part of a leaflet or both leaflets of the mitral valve extend above the plane of the atrioventricular junction during ventricular systole. the adenylate cyclase activity in mvp dys-autonomia was studied by extraction of enzyme from the erythrocytes from 62 normal su...

purpose: to determine the prevalence of keratoconus (kcn) in patients with mitral valve prolapse (mvp). methods: this descriptive study was conducted on patients with mvp at shahid rajaei hospital during 2003-2004. corneal topography was performed in 392 subjects with absolute mitral valve prolapse based on perloff’s major criteria. orbscan was carried out in suspected kcn cases. results: patie...

Degenerative mitral valve disease is responsible for the syndromes of billowing mitral leaflet, mitral valve prolapse (MVP), floppy mitral valve, and flail leaflet. The pathology of these is mainly caused by myxomatous infiltration and fibroelastic deficiency. In the 1960s, Reid and Barlow and colleagues proposed that mid to late systolic clicks and apical late systolic murmurs were of mitral v...

AIMS Deep clefts are a cause of early failure of mitral valve repair, but it is not known whether clefts represent normal morphology, or whether they occur more frequently in mitral valve prolapse (MVP). METHODS AND RESULTS Deep clefts were defined as indentations extending ≥ 50% of the depth of the mitral valve leaflet. Using trans-oesophageal echo (TOE), 3D zoom images were acquired of the ...

BACKGROUND Ventricular arrhythmias are common in patients with mitral valve prolapse (MVP). Previous studies have provided evidence that a higher degree of systolic mitral valve displacement and the presence of a thickened anterior mitral leaflet are related to an increased incidence of complex ventricular arrhythmias and risk of sudden death in these patients. The aim of our study was to inves...

The term mitral valve prolapse (MVP) is used for a particular subset of patients with hyperadrenergic dysautonomia. It occurs when part of a leaflet or both leaflets of the mitral valve extend above the plane of the atrioventricular junction during ventricular systole. The adenylate cyclase activity in MVP dys-autonomia was studied by extraction of enzyme from the erythrocytes from 62 norma...

In order to assess the reliability of the echocardiogram in detecting valvular vegetations in patients with mitral valve prolapse (MVP), echocardiograms from 85 consecutive patients with mitral valve prolapse were reviewed. Eleven patients had thick shaggy echoes confined to the anterior mitral leaflet; eighteen patients had shaggy echoes on the posterior leaflet; and five had abnormal echoes o...

Background-Mitral regurgitation (MR) of mitral valve prolapse (MVP) predominates in late

Mitral valve prolapse (MVP) is generally understood to be the systolic displacement of an abnormally thickened, redundant mitral leaflet into the left atrium during systole.1 This valvular abnormality has been associated with mid-systolic clicks, late systolic murmurs, and serious complications such as bacterial endocarditis, severe mitral regurgitation, and sudden death.2 Unfortunately, our un...
